Geometry

Question Analysis：
This question tests whether students can correctly evaluate when a transformation sequence qualifies as a glide reflection.
The main focus is on identifying if the translation is parallel to the line of reflection.

Key Concept Explanation：
Glide reflection = reflection over a line + translation parallel to that line
Here: reflected over x = 0 → a vertical line
Then translated 7 units left → a horizontal translation
→ These directions are perpendicular, not parallel → not a glide reflection

Step-by-Step Solution：
Reflection: x = 0 (vertical)
Translation: 7 units left → horizontal
These are perpendicular directions
So this transformation doesn’t satisfy the glide reflection condition
